Pinball is called pinball because it used to be literally nothing but a ball and pins. No flippers. The only method to obtaining a higher score was through nudging the ball into the proper places. The first game with flippers didn't come until much later. So I find it interesting (incorrect) when people assert that nudging is wrong, cheating, or not a part of pinball. Not only is it a part of pinball, it is arguably the most important aspect (both historically and currently) of pinball gameplay.
